Update RIPE's DNS Zonemaster
by Arsen STASIC 05 Jan '21

05 Jan '21

Hi, RIPE's DNS Zonemaster version might be outdated, because it does not support DNSSEC algorithm ED25519. This is the error message: Signature for DNSKEY with tag 52537 failed to verify with error 'Unknown cryptographic algorithm'. https://dnscheck.ripe.net/test/328db6c75665721b But the Zonemaster software (Versions: engine 4.0.3, backend 6.0.2, GUI 3.2.1) has already support for DNSSEC algorithm ED2551: https://www.zonemaster.net/result/c1607f01d96a8d60 It would be good if RIPE's Zonemaster could also list its version numbers. cheers, -Arsen

DNSSEC validation problem with ripe.net
by Anand Buddhdev 04 Dec '20

04 Dec '20

Dear colleagues, On 3 December, at around 15:40 (UTC+1), Matt Nordhoff and Peter van Dijk alerted us to a problem with the DNS resolution of certain names in ripe.net. Upon investigation, we discovered that a recent update in the zone had changed the status of some address records to glue records. This change was not handled correctly by our DNSSEC signer, and it left spurious NSEC records in the zone, which then caused validation failures. Eventually, around 20:00 (UTC+1), we forced the DNSSEC signer to fully re-sign the zone, and this fixed the problem. We have reported this issue to the developers of the DNSSEC signing software, and they are investigating. We are also adding some extra monitoring to our infrastructure, to detect such problems more quickly. Regards, Anand Buddhdev RIPE NCC
